The kinetics of Cr layer coated on TiNi films for hydrogen absorption

Abstract

The effect of hydrogen absorption on electrical resistance with temperature for TiNi and TiNi-Cr thin films was investigated. The TiNi thin films of thickness 800 A were deposited at different angles (θ = 0 • , 30 • , 45 • , 60 • and 75 • ) under 10 −5 Torr pressure by thermal evaporation on the glass substrate at room temperature. A layer of Cr of thickness 100Å was coated on the TiNi thin films. The changing rate of hydrogen absorption increases after Cr layer coating because Cr enhances the catalytic properties of hydrogen absorption in thin films. The rate of hydrogen absorption increases with temperature at lower range but at higher range of temperature it was found to decrease and also it was found that the hydrogen absorption increases with angle of deposition.

Dynamic Shadowing Growth and Its Energy Applications

“…In addition to solar cells, DSG nanostructures were also utilized as photoelectrodes for solar water splitting. Wolcott et al (2009) demonstrated a 0.1% photo-to-hydrogen efficiency with OAD TiO 2 nanorods, and they further showed that TiO 2 -WO 3 core-shell nanorods could further extend the photoconversion to visible wavelength range (Smith et al, 2011). Other TiO 2 -based nanostructures, such as Cr doped (Larsen et al, 2011) and CdSe decorated (Larsen et al, 2012) TiO 2 nanorods, were explored as the photoelectrodes for water splitting.…”

First Principles Investigation for H2 Dissociative Adsorption on Ni and Cr-Decorated Ni Surfaces - An Application to Alkaline Polymer Electrolyte Fuel Cell

“…Basically, Ni(111) and a monolayer of Cr atoms on Ni(111)-Cr ML /Ni(111)-surfaces are used for this purpose. Alloying and multilayer formation of Ni to other metals are some of the possible solutions to improve its reactivity while solving the problem on degradation [15,16]. Cr electrodeposits have been proven and are used extensively to protect the base metal from corrosion [17].…”
